The days of carburetors are long gone. They have been replaced by the modern fuel injection system, which provides cleaner emissions, better fuel economy, better performance and improved reliability. Today, several types of fuel injection systems exist on the market. The Multi-Port Fuel Injection (MPI) system is one of the most prevalent systems. This system was a significant improvement over the carburetor and throttle body injection systems it replaced as it provides much better fuel control.
The MPI system operates using one injector per cylinder, mounted in the intake runner positioned above each intake valve. As a result, fuel injected onto the intake valve, is mixed with the incoming air and then drawn into the combustion chamber. As the injectors are positioned close to the combustion chamber, fuel delivery is more immediate, precise, and effective. To ensure excellent performance of the whole system, the injectors must fire millions of times, precisely metering the fuel for each combustion event. A faulty multi-port fuel injector can lead to problems such as high emissions, decreased fuel economy, poor performance, etc.
If you are looking for high quality and durable injectors to increase your engine performance, turn to these E85 compatible injectors by DeatschWerks. The products are constructed especially for off-road use only and feature characterizations for data you need. The injectors excellent spray pattern and atomization ensure optimized idle and tuning. Each set of Deatschwerks injectors is balanced within 2% variation, making them easy to tune. This means better fitment, easier tuning, and increased reliability. To guarantee excellent performance, the products went through a multi-point dynamic flow test.380.07Brand: DeatschWerks Part Number: 21S-01-0650-4
